CONCLUSIONS AND SUMMARY 1. The morphology of nest development (stages) in Belonogaster griseus (Fab.) (Hymenoptera Vespidae Polybiini) serves as an introduction to a comparative study of the nests constructed by this genus. 2. Bilateral symmetry of the comb is established at construction of first cell. 3. The stages of predominantly longitudinal nest development, on an eccentric pedicel (laterinide nest), are characterized by the number of cells with eggs, larvae, mature larvae, and pupae and number of old, uninhabited, partially demolished cells. 4. Morphological parameters (compared with other Vespidi) such as divergence of the alveolar axes (perhaps the highest among social wasps), the lack of displacement in the transverse sections and its limited use in longitudinal sections, explain the «hammock-shaped» form of the nest and its limit of development, reached when the more peripheral cells present a horizontal—or nearly horizontal—position. 5. The construction techniques allowing the longitudinal deve... |
